Advantages of encrypting drives? Is the only advantage to encrypting your drive to keep someone from physically taking your drive and retrieving data? I would like to install freebsd and encrypt the swap partition but also am thinking about just encrypting the whole system. This pc will only be used for Apache, php, possibly ftp, and firewall. There will be nothing else on the system. My main question is if I were to want to encrypt the whole system, how could you accomplish this?
